On a number of implementations that I've seen there is a lack of correct antivirus exclusions which can cause stability issues. Unfortunately it happens more often than one would expect and I have therefore decided to document the once that most people are missing.

I have tried to document everything as good as possible based upon some notes that I have taken over the years – however I still recommend that you review the recommendation below so they actually match…

I had an email today from a customer who had forgotten their admin password used for logging on to their license administration console. Below is how you can reset the password. 1) Open the "server.xml" file located in the C:Program FilesCitrixLicensingLSconf directory 2) Find the entry that looks something like this: firstName="System" id="admin" lastName="Administrator" password="(ENC-01)UaFz17cJ2oNQ+LkskjkzUyVV5ZcmaoJCDCiuiusbB6zk2P0uR" passwordExpired="false" privileges="admin"/>; 3) Erase the contents between the double quotes after "password=" 4) Enter a plaintext password so it looks like this: password="test" 5) Change the passwordExpired value to be "true" 6) Save the server.xml file. 7) Restart the licensing services. 8) Close and re-open the…

Do you know the difference between Receiver and Receiver Infrastructure? What about Receiver Enterprise, Receiver Inside or Receiver Updater? Did you hear about the upcoming One Receiver? Are you confused as most of my customer when it comes to that topic? Good because in this article I will try to explain the differences and the Citrix Receiver idea! The Idea of Citrix Receiver Before the release of Receiver, Citrix had various "Clients" for different reasons like the ICA Client, the Secure Access Gateway Client, Password Manager Client etc. with the tendency of more clients to come. Now if you are using…

With Receiver 3.x client, administrators might want to configure the default behavior for device access when connecting to a Citrix XenDesktop environment.

This helps to simplify management during certain maintenance and disaster recovery scenarios.” But what does it exactly mean and how should it be configured? I’m following this best practice for many years and I would like to share few information about how to use it and what are the…

This is actually very common problem in many environments – Web Interface andor particular consoles (mostly MMC-based) are slow to start – there is actually KB article that describes a workaround for this issue. I consider this to be one of the tweaks that many people often implement, but don’t really understand the consequences and the reasons why it helps, so I’ve decided to write a small blog post about this topic. What is certificate revocation list? So, you’ve got your certificate issued, right? But now you can ask yourself – what should I do in case that certificate was…
